Well I've tried RWS Superdomes, AirArms and JSBs in my Mk3 FT-R .177Superdomes - no specific head size. Went all over the place.AirArms 4.52 - pretty good but sent a few fliers here an there.JSBs - 4.50s - fliers 4.51 - fliers. 4.52 and 4.53 - LOVES 'EM.

There are so many variations it seems that you just have to try a few makes and head sizes. - and then STICK with em!

Just had my first range time with my new Wolverine .177 to zero the scope. After using its first 40 pellets to get it zeroed I must say I'm more than happy with getting a 10 shot grouping like this over 25m using .177 Exact Premium Diablo ....

I have just brought a lovely Mk3 FT version b2 I think it has the regulator fitted, I'm looking for the best grouping pellet I've tried Jsb exact and rws superdome both in 4.52 as that was what my HW100T liked grouping was ok but not what I expected should I try 4.51 or 4.53 which would be best?Cheers
